Kawakubo (LSU)\nreport on behalf of the MAXI team:\n\nWe examined MAXI/GSC all-sky X-ray images (2-20 keV) \nafter the LVC trigger S190720a at 2019-07-20 00:08:36.747 UTC (GCN 25115).\n\nAt the trigger time of S190720a, the high-voltage of MAXI/GSC was off,\nand it was turned on at T0+1076 sec (+17.9 min).\nThe first one-orbit (92 min) scan observation with GSC after the event covered 90% \nof the 90% credible region of the bayestar skymap from 00:26:32 to 01:35:16 UTC (T0+1076 to T0+5200 sec).\n\nNo significant new source was found in the region in the one-orbit scan observation.\nA typical 1-sigma averaged upper limit obtained in one scan observation\nis 20 mCrab at 2-20 keV.\n\nIf you require information about X-ray flux by MAXI/GSC at specific coordinates,\nplease contact the submitter of this circular by email.",
